More than 125 Years of Innovation 
Honeywell's roots reach to 1885, when an inventor named Albert Butz patented the furnace regulator and alarm. He formed the Butz Thermo-Electric Regulator Co., Minneapolis, in April, 1886, and soon invented a device he called the "damper flapper” – an ingenious predecessor to the modern thermostat. 

Meanwhile, in Wabash, Indiana... 
In 1904, a young engineer named Mark Honeywell – from whom our name originated – was perfecting the heat generator as part of his plumbing and heating business. Two years later, he formed the Honeywell Heating Specialty Co. Incorporated, specializing in hot water heat generators.

In 1927, Minneapolis Heat Regulator Company and Honeywell Heating Specialty Co. merged to form the Minneapolis-Honeywell Regulator Co., and became the largest producer of high-quality jeweled clocks. W. R. Sweatt became Chairman and Mark Honeywell became President. The company quickly grew as it began to tackle more challenges, including industrial controls and indicators.

Since those early days, Honeywell has never ceased innovating.  In the 1980's Honeywell made a customer centric decision to develop a distribution network.  Loy Instrument, with our long Honeywell history, application engineering and product knowledge was one of four companies in the United States asked to represent the brand in this new and exciting model.  This made Loy Instrument the oldest Honeywell distributor in the nation along with the three other partners.

Honeywell has continued to grow and expand for generations.  Few markets today are untouched by the Honeywell brand and it's teams of employees and partners.  Loy Instrument represents and or distributes for Honeywell in many of their premier lines.  Some of the lines that we represent at Loy Instrument include the following:
